modifying a sound fob is a flaky unreliable (and in alot of cases for people unattainable because of the size what you have to solder) mess. Wires fall off because there is no good way of attaching them reliably. I developed the software for this thing using those, and I cant tell you how nice they were to have (although annoying because of the numerous times a wire would break), but I am now OVERJOYED to have a real, physically reliable device with real connections solderable by a real human being. If a difference of $60 or so is in any way significant to you, then by all means modify the generic fobs. We went way out of our way to ensure that the software/technology would work identically regardless of whether you bought a "real" one or modified a generic one.
